branchiomotor nuclei
collective term for those motoneuronal nuclei of the brainstem (n. ambiguus, facial motor nucleus, and motor nucleus of the trigeminus) that develop from the branchiomotor column of the embryo and innervate striated muscle fibers (muscles of mastication, facial musculature, pharynx, and vocal cord muscles) associated with the branchial arches. (The term pharyngeal arch is commonly used in humans because gills do not appear during development in this species.)Synonym(s): special visceral efferent nuclei, special visceral motor nuclei
